She said it was a bit of a case of life imitating art, after
playing pregnant women in her recent films.

"It is strange the last three films I've done I have been
pregnant," Collette said.

"I'm just like, what is the universe trying to tell me.

"But I think everything happens when it's meant to."

Collette, who married Galafassi in January 2003, did not say
what stage her pregnancy was at.

The Sydney-born actress and singer recently said she was looking
forward to motherhood and had become aware that her body clock was
ticking.

On Saturday, Collette performed with her band The Finish - with
Galafassi on drums - during Sydney's Live Earth concert, which
attracted a 50,000-strong crowd as part of a round-the-globe series
of shows designed to raise awareness of climate change.

Collette said it was great event to be a part of.

''That was such an amazing day,'' she said.

''I was nervous leading up to it. I was having the pounding
heart and the churning stomach, and then as soon as I got there I
just calmed down.

''But it's an amazing feeling to stand up there in front of so
many people, especially knowing why everyone was there.''

Collette said she was now looking forward to some down time.

''I've been working non-stop since April of last year, and I
just finished with Live Earth on Saturday, and I think I'm going to
take a little bit of time off,'' Collette said.
